| Abstract |
This project describes how power plants can make their own steam silencers. The silencer is for dry steam based on orifice plates. Its simple design makes it economically viable. The silencer reduces significantly the noise produced by steam discharges where it is needed to relieve pressure. The prototype on which the experiments were made, handles 4 T/h of steam at 160 psig, and it reduced the noise level from 140db to 107db (by 33db). The equipment consists of plates with several orifices in each plate that reduce the pressure in stages. |
